I really like this piece, especially the eyes and expression, from what one can see this is just the way he would look, the pained expression going along with sometimes pained lyrics. Some say yellow is the colour of cowardice, in this case I believe it shows a sense of him being afraid of the world. The microphone and the stage are the boundary, and the crowd looking on are the intruders, looking into his world, wanting more and more until finally they've taken everything.
